Charles P. Stone to Seth Williams, September 2, 1861

Maj. S. WILLIAMS, Assistant Adjutant-General, Hdqrs. Army of the Potomac : MAJOR: I have the honor to report that two or three regiments broke up their camp near Leesburg this forenoon, and marched nearer the river, the bulk of two regiments approaching Conrad’s Ferry. They strengthened all their pickets throughout the line. There is no appearance of re-enforcement. My impression is that the movement was caused by a feeling of alarm lest we should attempt a crossing in force, as one of the advanced pick- – ets of the Tammany regiment crossed the river last night and cut out and brought over a large ferry-boat. I have caused the outposts to be strengthened by infantry and artillery, but do not anticipate any advance of the enemy.

Very respectfully, I am, your obedient servant,
